Slit chisel

Compared to conventional moile points and flat chisel, our original slit structure increases the heat-treated surface area, greatly improving wear resistance.
By providing a slit-shaped groove, the discharge of crushed pieces is promoted, and the crushing efficiency is also improved.
The unique shape optimizes the wear balance, and it is also a major feature that the sharp state lasts for a long time even if it is shortened.
